RAB3A, Recombinant, Human, aa1-220, His-tag (Ras-related Protein Rab-3A)

Rab3A belongs to the small GTPase superfamily, Rab family. It is a small, Ras-like GTPase expressed in neuroendocrine cells, in which it is associated with secretory vesicle membranes and regulates exocytosis. This protein could play a role in neurotransmitter release by regulating membrane flow in the nerve terminal. Purified by using conventional chromatography techniques. Source: Recombinant corresponding to aa1-220 of human RAB3A, fused to His-tag at N-terminal, expressed in E.coli.
